Drilling sites are focus of application reports

A series of application reports focuses on worldwide drilling sites.

Three recent additions to these 2-4 page educational reports look at the utilization of truck-mounted rotary rigs used in coalbed methane and natural gas production.

Application reports 7, 8, and 9, respectively, include a tribute to Noah Horn of Noah Horn Well Drilling Inc., Vansant, Va.; documented use of rigs in rural Missouri by Pense Bros. Drilling Co. Inc., Fredericktown, Mo.; and rig operations in Alberta by the drilling division of BlackWatch Energy Services Trust, Calgary. The reports include location photos and comments from site supervisors.

New memory sensor for coiled tubing operations

DataCoil, a new memory sensor for coiled tubing use, combines multiple sensors into a compact module.

The module accompanies the bottomhole assembly (BHA) and monitors parameters such as pressure, temperature, inclination, compression, and tensile and impact loads.

The system was deployed recently in Alaska, where it was subjected to 24,000 impacts greater than 10,000 lb each over a 30-min interval during a high-profile fishing operation. During vibratory impacting, the tool continued to acquire pressure, temperature, and strain data, performing without interruption, the firm reports. The tool has been used on more than 12 wells for various applications since. The system can be deployed “in field” for extended periods of time on a single battery charge, typically more than 6 months, the firm says.

The system can be applied in the following BHA configurations:

  • Perforating.
  • Fracturing.
  • Inflatable packer setting.
  • Bridge/plug setting/retrieval.
  • Heavy duty fishing operations.
  • Milling operation.
  • Vibratory hammers.
  • Hydraulic single shot hammers.
  • Tractor deployment/measurement.
  • Sliding sleeve manipulation and confirmation.

It supplies information as follows:

  • Data analysis of coil tubing loads.
  • Surface tensile vs. BHA loading.
  • Surface applied pressure vs. actual BHA pressures.
  • Actual BHA inclination for friction analysis.
  • Actual forces applied during impacting with the ability to monitor change with pressure analysis.
